This research is conducted as a test of the level of satisfaction of residents in the Central Highlands of Vietnam, specifically in DamB’ri Commune, Bao Loc City, Lam Dong Province. The survey of 100 residents at 4 hamlets of DamB’ri Commune did not record statistically significant differences in the level of satisfaction of participants for the criteria including sexes, educational level, occupation, and working age. Nevertheless, there was a statistically noticeable higher level of satisfaction with Health Insurance for participants who are officers at Hamlet 3. The results of the multiple linear regression method, including 7 independent variables and 1 dependent variable, based on the Health Belief Model (HBM), show that the awareness about restrictions and benefits are the core factors impacting the level of satisfaction of residents. The results also provide crucial evidence for authorities and policymakers to devise plans and solutions to increase the level of satisfaction with Health Insurance for people in Central Highlands.

This is a descriptive study to find out students’ awareness about the benefits and harm that they have experienced from using the AI tools during their learning process. The study was founded on a survey and an interview among majored-English students at Thu Dau Mot University. The data was then This descriptive study aims at finding out students’ awareness about the benefits and harm that they have experienced from using AI tools during their learning process. A four-section survey including open and closed-ended questions was sent out, and 193 majored-English students at Thu Dau Mot University responded randomly. The striking finding is that although students preferred AI tools to support their learning, they themselves accepted the benefits gained and the challenges faced were just a little over the average. In particular, the participants confirmed that AI tools contribute much to the fast speed of their academic work completion, but AI also makes them passively think, become inflexible, and somewhat limit the ability to equip knowledge for their English language competence.

The study aimed to evaluate disease knowledge, perceived susceptibility and compliance behaviors of post-kidney transplant patients as well as assess relationship between disease knowledge, perceived susceptibility and compliance behaviors. A descriptive cross-sectional study conducted on 153 post-kidney transplant patients from March to June 2024 at Outpatient Department of Cho Ray hospital. The result showed that the majority of respondents have a lack of knowledge regarding medication and lifestyle change post kidney transplantation. While perceived susceptibility of respondents were at a fair level. Majority of respondents has a low level of perception regarding barriers to adherence and susceptibility to transplant rejection, while they have a good level of perception regarding benefits of adherence to treatment with immunosuppressive medication. Compliance behavior of post kidney transplant adults was at a good level. Majority of respondents had good compliance behavior regarding medication, while exercise and psychological adaptation was the lowest level of compliance behavior. There are positive relationships between Compliance behaviors and disease knowledge (r = 0.49, p < 0.001); perceived susceptibility (r = 0.45, p < 0.001) and perceived susceptibility plays a partial mediating role between knowledge and compliance behaviors and the mediating effect accounted for 31% of the total effect of disease knowledge on compliance behavior. The study also indicated that educational level (ꞵ = 0.93, p = 0.020), duration of transplant (ꞵ = 0.20, p = 0.012) are predictive factors of compliance behavior among post – kidney transplant patients. Educational interventions targeting both knowledge and health beliefs, particularly for older individuals, could improve adherence to treatment and overall health outcomes.

In physics, the majority of natural events have been researched and described using differential equations, each having its own initial and boundary conditions. These differential equations contain a large number of fundamental constants as well as other model parameters. They add to the equation's complexity and rounding errors, making the problem more difficult to solve. In this work, we provide a method for transforming these physics differential equations into dimensionless equations, which are significantly simpler. Nondimensionalization, by suitably substituting variables, is the process of removing some or all of the physical dimensions from an equation that contains physical quantities. Some benefits of these dimensionless equations include that they are simpler to identify when using well-known mathematical methods, need less time to compute, and do not round off errors. Through several examples we discuss, this method is useful not just in quantum mechanics but also in classical physics.

Abstract: Urban agriculture is a highly concerned issue during the period of rapid urbanization in Vietnam. Research aims to propose a cultivation process for cultivating oyster mushrooms, utilizing coffee grounds from coffee businesses as a resource. This approach promotes circular economy principles, generating economic benefits for households while protecting the environment and being suitable for urban areas. The study conducted experiments on grey oyster mushrooms using different mixtures of coffee grounds and rubber wood sawdust at the following ratios: 0%, 25%, 50%, 75%, and 100% coffee grounds/rubber wood sawdust, filled into bags with a weight of 1.2kg. The research results showed that disease infection rates were mild in the 0% and 25% mixture ratios, while the remaining ratios exhibited moderate to severe infection levels. The highest mushroom yield was observed in the mixture ratio of 25% coffee grounds, with an average number of mushroom ears per bag reaching 29.7grams/bag, the dry weight is 63.8 grams/bag, with an average size ranging from 3 to 14 cm and a moisture content of 79.5%. The fastest colonization speed on the substrate is achieved by 25%, 50% coffee grounds blend, which fully colonizes the bag in a period of 25 to 35 days, the shortest time compared to the 75% and 100% coffee grounds blends, which take 40 to 45 days. The experimental results show that the 25% coffee grounds: 75% rubber sawdust blend is suitable for urban mushroom cultivation models and can be expanded on a large-scale farm, contributing to minimizing environmental pollution, utilizing limited urban land area, and providing high economic efficiency.

Declining supplies of fossil fuels, increasing population, global industrialization and demand for transportation fuels has triggered an increase in the demand for renewable energy sources. To address such problems most of the green research in the recent years has focused on the development of bioethanol (23 MJ/L) as a substitute to conventional gasoline (34.3 MJ/L) based fuels owing to the similarity in energy density values in addition to several other advantages (American Council on renewable energy, 2010). Second-generation biofuels are derived from lignocellulosic biomass or woody crops, mostly coming from agricultural residues. Extraction of fuel from such biomass is difficult because of their recalcitrant nature (corn stover, rice straw, wheat straw, sugar cane and sweet sorghum). Lignocellulosic fuel has the potential to solve several problems (food competing with fuel) that are currently associated with first generation biofuels. Moreover, lignocellulosic fuels can supply a larger proportion of the global fuel leading to sustainability at lower cost, and with greater environmental benefits (Liz Marsall, 2009). The production of ethanol from the complex sugars in leaves and stalks is a promising strategy to radically broaden the range of possible ethanol feedstock. Keywords: lignocellulose, bioethanol, biomass, pretreatment, hydrolysis, fermentation.
